Title: Sticking method and sticking device for microlens
Inventor: YOSHIKAWA MASAO
IPC: G02F1/1335
Filed: 1992-11-30
Abstract: PURPOSE:To provide the sticking method capable of improving productivity and reliability and preventing the degradation in image grade by preventing the intrusion of air bubbles and the nonuniformalization of a cell gap at the time of sticking a liquid crystal display element and a microlens. CONSTITUTION:The microlens 1 is gradually lowered by repeating the lifting operations of lowering the microlens 1 at the predetermined descending distance in an arrow A1 direction from the start point where descending is started, then rising the microlens in an arrow A2 direction at an ascending distance shorter than the descending distance to displace the microlens down to the end point lower than the start point at the time of sticking the liquid crystal display element 2 and the microlens 1. The lifting operation is thereafter stopped when the thickness of the layer of an adhesive layer 3 attains the predetermined thickness and the microlens 1 is lowered by its own weight.

Title: Liquid crystal display device and preparation thereof
Inventor: CHIYOU SHIYUUEN
IPC: G02F1/1339
Filed: 1995-11-15
Abstract: PROBLEM TO BE SOLVED: To obtain a liquid crystal display device having a high contrast ratio by selectively praying the spacers sprayed between assembly parts to the non- pixel parts of a liquid crystal display element. SOLUTION: A power source is electrically connected to respective transparent conductive films 24 of the second assembly part 2b for keeping the spacers 26 electrified to a positive (+) charge and the same polarity, i.e., positive (+) charge is imparted thereto. The spacers 26 are pressurized in this state by the gaseous nitrogen from a housing container. When the spacers are sprayed above an alignment layer 25 by an injector connected to the housing container by which the spacers 26 are guided and sprayed on the part of the non-pixel parts (B) and this reason is that the spacers 26 are prevented from being sprayed onto the front surface parts, (i.e., pixel parts A) of the transparent conductive film 24 on account of the repulsion by the repulsive force of the same polarity as the spacers are guided to the sections of the non-pixel parts (B).  As a result, the spacers 26 are sprayed only to the sections corresponding to the non-pixel parts B above the layer 25.

Title: Method for measuring ghost by wave matching
Inventor: KOMIYA NORIAKI
IPC: H04N17/00
Filed: 1996-11-18
Abstract: PROBLEM TO BE SOLVED: To clarify the method for measuring ghost accurately by matching synthesized ghost wave with the ghost wave of known wave detected by synchronizing. SOLUTION: In this method measuring for ghost, in-phase component wave g of known wave and the rectangular component wave h are used and a ghost wave is synthesized Z by using a ghost parameter. By changing the ghost parameter so as to minimize the sum of squares of errors from the measured ghost wave, the ghost parameter is obtained, By this, synchronizing detection of two rectangular axes is unnecessary. And ghost can be exactly measured. For renewing the ghost parameter, wave delay and differential of the delay are needed to obtain. If this signal processing is done in a time range, an interpolation wave need to be obtained corresponding to slight delay time at every moment in the fitting process, which makes it complicated.  By performing this signal processing in the frequency range, the delay time and the differential of the delay can be treated as a transmission function and thus signal processing is made easy.
